GD32F405RET6 GD Microcontroller Unit MCU LQFP-64

Introduction

The GD32F405xx device belongs to the connectivity line of GD32 MCU Family. It is a new 32-bit general-purpose microcontroller based on the ARM® Cortex®-M4 RISC core with best cost-performance ratio in terms of enhanced processing capacity, reduced power consumption and peripheral set. The Cortex®-M4 core features a Floating Point Unit (FPU) that accelerates single precision floating point math operations and supports all ARM® single precision instructions and data types. It implements a full set of DSP instructions to address digital signal control markets that demand an efficient, easy-to-use blend of control and signal processing capabilities. It also provides a Memory Protection Unit (MPU) and powerful trace technology for enhanced application security and advanced debug support.

The GD32F405xx device incorporates the ARM® Cortex®-M4 32-bit processor core operating at 168 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 3072 KB on-chip Flash memory and 192 KB SRAM memory. An extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer up to three 12-bit 2.6M SPS ADCs, two 12-bit DACs, up to eight general-purpose 16-bit timers, two 16-bit PWM advanced-control timers , two 32-bit general-purpose timers, and two 16-bit basic timers, as well as standard and advanced communication interfaces: up to three SPIs, three I2Cs, four USARTs and two UARTs, two I2Ss, two CANs, a SDIO, USB device/host/OTG FS and HS. Additional peripherals as Digital camera interface (DCI) is included.

The device operates from a 2.6 to 3.6V power supply and available in –40 to +85 °C temperature range. Three power saving modes provide the flexibility for maximum optimization of power consumption, an especially important consideration in low power applications.

The above features make GD32F405xx devices suitable for a wide range of interconnection and advanced applications, especially in areas such as industrial control, consumer and handheld equipment, embedded modules, human machine interface, security and alarm systems, graphic display, automotive navigation, drone, IoT and so on.
